Iceland) report on behalf of a larger collaboration:\n\nWe observed the field of GRB 160607A (Ukwatta et al., GCN 19502) with \nthe Nordic Optical Telescope (NOT), located in La Palma (Canary \nIslands). Observations were carried out at large airmass (~3) in the \nSDSS i filter, for a total of 20 min on source, at a mean epoch 2016 \nJune 8.19 UT (0.725 days after the BAT trigger).\n\nWithin the refined XRT position (Goad et al., GCN 19503), we detect a \nsingle, faint source at coordinates (J2000):\n\nRA = 00:54:40.14\nDec = -04:56:53.3\n\nCarrying out photometry against the SDSS catalog, we derive a magnitude \ni = 23.45 +- 0.20 AB. As this value is fainter than the SDSS limit, and \nas we lack variability information, we cannot presently conclude whether \nthis source is the afterglow of GRB 160607A. Further observations are \nplanned, but will be probably delayed until the field has a better \nvisibility from La Palma.",
